Product Description
Every hard training day comes down to two moments: the one before you go, and the one after you've emptied the tank. Preparing for the hard day, and recovering from it, are what separate the normal workouts from the great ones.
KA-EX built two drinks for exactly that — and together, they cover the full training cycle.
Before: KA-EX Creatine EAA + Booster
Creatine That Actually Reaches Your Muscles – Most ready-to-drink creatine products have a hidden problem: creatine is chemically unstable in liquid. By the time you drink it, it's already broken down into creatinine — the inactive version your body can't use. KA-EX's patented VICAP® push-cap keeps the full 3g Creapure® dose dry inside the cap until the moment you press it open. Real dose. Every time.
A Complete Pre-Workout Stack – Beyond creatine, each serving delivers 3.5g of essential amino acids (the building blocks your muscles need during hard efforts), 105mg caffeine for focus, 1g L-citrulline to widen blood vessels and push more oxygen to working muscles, 500mg betaine for power output, and key electrolytes to keep everything firing. One drink replaces what used to take four supplements.
After: KA-EX Cortisol Stress Reducer
Fix The Cortisol Problem – The Cortisol Stress Reducer targets the 48-hour post-workout cortisol window with 100mg of phosphatidylserine — the compound that tells your body to dial down stress hormones — plus L-tryptophan for deeper REM sleep and L-glutamine to rebuild what training breaks down. Three clinical trials and five years of Swiss research back the formula: 36% faster cortisol reduction, 15% improved REM sleep, and a 10% improvement in HRV patterns.
Swiss-Engineered Recovery– Phosphatidylserine tells your body to dial down stress hormones. L-tryptophan supports deep REM sleep. L-glutamine and targeted amino acids rebuild what training breaks down. This goes way beyond basic electrolytes.
How to Use the KA-EX Two Drink System
Before Training (15–30 min pre-workout): Press the VICAP® push-cap on the Creatine EAA+ Booster to release the creatine dose, shake briefly, and drink. Powder version: mix one sachet into 16 oz of water.
After Training (immediately post-workout): Mix one sachet of Cortisol Stress Reducer in 10–17 oz of cold water and drink right away. Take a second serving 24 hours later, including rest days — cortisol doesn't reset overnight.
Pro Tip: Creatine builds through daily accumulation, so take the Booster every day — even on easy days — to keep your stores loaded for when the effort counts.
KA-EX is the official supplier to PSG, Tudor Pro Cycling Team, and the Swiss National Soccer Team, trusted by Olympic gold medalists and F1 drivers. Fabian Cancellara calls it "the perfect complement for top performance." Stop leaving the hardest half of training to chance.

KA-EX Performance Pack FAQ's
Everything you need to know before getting started.
Two drinks that cover the full training cycle: Creatine EAA+ Booster for before your workout, and Cortisol Stress Reducer for after.
Creatine breaks down into inactive creatinine once it sits in liquid. The VICAP® push-cap keeps your full 3g Creapure® dose dry and sealed until you press it open right before drinking — so you get the real dose every time, not a degraded one.
Each serving also delivers 3.5g essential amino acids, 105mg caffeine, 1g L-citrulline, 500mg betaine, and electrolytes, one drink covering what would normally take four separate supplements.
It targets the 48-hour cortisol spike after hard training with 100mg phosphatidylserine, L-tryptophan for deeper REM sleep, and L-glutamine to help rebuild what training breaks down.
